I'm from Chicago and am an expert on Chicago dogs (I even made the pilgrimage to the vienna hot dog factory!)have eaten hot dogs from all the local neighborhoods in Denver. This is simply the best Chicago dog out there. The Italian beef is also pretty authentic (get it wet with hot peppers). Good eats for an incredible price. Chicagoans: This is the real deal.
Best Hot Dog Denver 2011 - Mile High Vienna Stand
300 Santa Fe Drive
Denver, CO 80223
Cubs ticket stubs, Harry Caray photos and other Chicago sports paraphernalia line the walls of Mile High Vienna Stand, channeling the city that's famous for a favorite sports snack: the Chicago dog. Naturally, that's what Mile High Vienna serves. The bona fide Chicago dog starts with a pungent Vienna beef dog, then adds chopped white onions, pickled sport peppers squirting seeds and juice, nuclear-green sweet relish, a dill pickle spear, thin slices of translucent tomato, a ribbon of mustard and a healthy dusting of celery salt, all piled on a perfectly steamed poppyseed bun. Served with a clip of fries, it's as close as you'll get to the Windy City without leaving the Mile High.
